Your credit score and your FICO score are not the same thing

A credit score is any number a lender uses to predict whether you'll pay back borrowed money. A FICO score is one specific type of credit score, made by the Fair Isaac Corporation. Think of it this way: all FICO scores are credit scores, but not all credit scores are FICO scores. When a lender pulls your score, they might get a FICO score, a score from Vantage Score (a competitor), or a score built just for that lender's own use.

The confusion happens because FICO scores are the most common. Most banks, credit card companies, and mortgage lenders use them. But other scoring models exist and are growing in use, especially for auto loans and rental applications. Knowing the difference matters because your score can vary depending on which model a lender runs.

Key Takeaways

  • FICO is one brand of credit score made by Fair Isaac Corporation; "credit score" is the umbrella term for any number lenders use to assess risk.
  • FICO scores range from 300 to 850 and weigh payment history (35%), amounts owed (30%), length of credit history (15%), credit mix (10%), and new credit (10%).
  • Other scoring models like Vantage Score and industry-specific scores use different ranges and weightings, so your number can shift depending on which lender pulls which score.
  • You can see your FICO score free once per year through Equifax, Experian, and TransUnion at AnnualCreditReport.com, the official government site.
  • Lenders do not have to tell you which scoring model they used, so ask directly if you want to know whether they pulled your FICO or something else.

How FICO scores are built and what they measure

A FICO score is a three-digit number between 300 and 850 that predicts the likelihood you'll pay a debt on time. It is built from data in your credit reports at the three major bureaus: Equifax, Experian, and TransUnion. FICO does not collect the data itself—the bureaus do. FICO buys that data and runs it through their formula.

The formula weights five categories. Payment history makes up 35 percent of your score—whether you paid on time, how late you were, and how often it happened. Amounts owed (how much you currently carry relative to your limits) is 30 percent. Length of credit history is 15 percent. Credit mix (having both revolving credit like cards and installment credit like loans) is 10 percent. New credit inquiries and recently opened accounts are 10 percent.

FICO updates your score whenever the bureaus update your file, which can happen daily. You do not have a single FICO score—you have three, one from each bureau, because each bureau holds slightly different information about you.

Other credit scoring models and how they differ

Vantage Score is the main competitor to FICO. It also ranges from 300 to 850 but weights the categories differently: payment history is still dominant, but new credit and available credit get more emphasis than FICO gives them. Vantage Score also allows scoring people with thinner credit files—those with less history—which FICO cannot always do.

Beyond Vantage Score, lenders build proprietary scores just for their own use. A bank might have a mortgage score, an auto lender might have an auto score, and a credit card company might have a card score. These are not sold to the public and you will never see them. They use the same underlying credit report data but explore different weights to different factors because the risk profile of a mortgage borrower differs from that of a car buyer.

Industry-specific scores also exist. Mortgage lenders sometimes use FICO scores specifically designed for mortgage lending, which emphasize mortgage payment history more heavily than a general FICO score does. The range and formula can shift depending on the industry.

Why your score changes depending on who pulls it

Your credit score can vary for three reasons. First, the three bureaus hold slightly different information, so your Equifax FICO score may differ from your Experian FICO score. Second, different scoring models weight the same data differently, so a FICO score and a Vantage Score built from the same report will not match. Third, lenders sometimes use older versions of a scoring model—FICO has released FICO 8, FICO 9, and FICO 10, and not all lenders have upgraded.

A swing of 20 to 50 points between scores is normal and not a sign of error. A swing of 100 points or more suggests either that the bureaus have different information about you, or that a lender is using a very different scoring model than you expected.

Where to see your actual FICO score for free

The federal government requires each of the three bureaus to give you one free credit report per year. Go to AnnualCreditReport.com—this is the official site run by the three bureaus themselves. You can order all three reports at once or stagger them throughout the year. The reports show your account history and payment record but do not include your FICO score.

To see your actual FICO score, you have a few options. Equifax, Experian, and TransUnion each offer free FICO scores directly through their own websites, though they may ask for a credit card to verify your identity. Some credit card issuers and banks also show your FICO score free in your online account. If you have a mortgage or auto loan, your lender may provide it. Many of these free scores are updated monthly.

Paid services like myfico.com (run by Fair Isaac Corporation itself) offer more detailed breakdowns and let you see how changes to your accounts would affect your score, but the free options cover what most people need.

What lenders actually use and how to ask

Most mortgage lenders use FICO scores, specifically FICO 8 or FICO 9. Most credit card issuers use FICO scores. Auto lenders are more mixed—some use FICO, some use Vantage Score, and some use their own model. Rental companies and utilities increasingly use Vantage Score or non-traditional scores that factor in rent and utility payment history.

You can ask a lender directly which score they use before you explore. Many will tell you. If they say "credit score" without naming the model, follow up and ask whether it is FICO or something else. Knowing which model they use helps you understand why your score with one lender differs from another.

Frequently Asked Questions

Is my FICO score the same across all three bureaus?

No. Each bureau holds slightly different account information, so you have three FICO scores—one from Equifax, one from Experian, and one from TransUnion. Differences of 10 to 30 points are common. A lender might pull from just one bureau or all three, depending on their process.

Why is my credit score different on my bank's website than on AnnualCreditReport?

Your bank likely shows you a Vantage Score or their own proprietary score, not a FICO score. Even if it is a FICO score, it may be from a different bureau than the one you checked elsewhere, or it may be an older version of the FICO formula. Ask your bank which model they display.

Does checking my credit score hurt my credit?

No. Checking your own score is a soft inquiry and does not affect your FICO score. Hard inquiries—when a lender checks your score because you applied for credit—can lower your score slightly, but checking it yourself never does.

Can I improve my score faster by using a different scoring model?

No. Your underlying credit behavior is what changes your score. If you pay on time and lower your balances, all scoring models will reflect that improvement. Different models may show the improvement at slightly different speeds, but the direction is the same.

What score do I need to get approved for a loan?

It depends on the lender and the type of loan. Mortgage lenders typically want 620 or higher for conventional loans, though 740 or higher gets better rates. Credit card issuers vary widely. Auto lenders work with scores as low as 500. Ask the lender what their minimum is before you explore.
